The prohibition of betrayal Sahih Muslim 1738 b
Arabic hadith text
حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا عَبْدُ الصَّمَدِ بْنُ عَبْدِ الْوَارِثِ، حَدَّثَنَا الْمُسْتَمِرُّ بْنُ الرَّيَّانِ، حَدَّثَنَا أَبُو نَضْرَةَ، عَنْ أَبِي سَعِيدٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم "لِكُلِّ غَادِرٍ لِوَاءٌ يَوْمَ الْقِيَامَةِ يُرْفَعُ لَهُ بِقَدْرِ غَدْرِهِ أَلاَ وَلاَ غَادِرَ أَعْظَمُ غَدْرًا مِنْ أَمِيرِ عَامَّةٍ "
Translation
It is narrated on the authority of Abu Sa'id that the Messenger of Allah (ﷺ) said
On the Day of Judgment there will be a flag for every person guilty of the breach of faith. It will be raised in proportion to the extent of his guilt; and there is no guilt of treachery more serious than the one committed by the ruler of men.
